In industrial production and real life, the application range of electric motors is very wide. However, in practical use, rotor imbalance problems often occur. The main reason is that the center of mass of the rotor deviates from the actual center of inertia main axis due to design characteristics, process accuracy, manufacturing accuracy, uneven material, and installation errors, resulting in significant imbalance force of the motor rotor during high-speed rotation. When the rotor rotates at high speed in an unbalanced state, the higher the rotational speed, the greater the inertial force, the greater the deflection of the rotor, and the greater the internal force inside the rotor. The increase in deflection further increases the imbalance of the rotor, ultimately causing severe vibration and noise throughout the entire machinery, accelerating the wear and tear of internal parts, reducing the accuracy and service life of the machinery, and in severe cases, causing cracking of welds. This not only increases maintenance costs, but also increases maintenance costs, It also affects the normal production of enterprises and causes huge losses, so solving the dynamic balance problem of rotors is a hot topic for enterprise researchers.
